IMPROVEMENT m :S'ULKY-PLOWS.

Specification forming part of Letters Patent No. 76,836, dated May 2,1876; application filed January 21, 1676. I

skeleton frame, and the depth of furrow tobe'" cut is regulated byahand-lever near the seat.

The details of this invention will now be described.

In the drawing, forming part of this specification, Figure 1 is a sideelevation of the plow. Fig. 2 is a front elevation. Fig. 3 is'a plan,and Fig. 4 is a view of a detached plow and single beam, to be usedsingly in place of the two plows and beams shown attached to the plow inthe preceding figures.

In these figures, A A are the beams of the plow. B is its tongue, and Othe skeleton axle-tree, terminating at one end in a vertical rod, whichI call the axle a. D is an ordinary wheel, and D a wheel attached to awheel spindle d having its axle inclined down- 'wardly from thehorizontal, which inclination consequently gives said wheel aninclination from the vertical. It can, however, be adjusted to anydegree of angularity by means of the block d ratchet-disks d d, andsetscrews 8 s. The rim of the wheel D instead of having an ordinary flattire, is provided with an angular pointed rim, 1'.

E E are the plows proper, or cutters, at-

' tached by slotted standards to the rear ends of the beams A A. Theaxle-tree O is braced by two rod-braces, c c, which serve as guides forthe slotted. plates 0 e, to which are bolted the beams A A. To the topof the axle G is secured in bearings a shaft, Gr, extended through asector G To the shaft G is secured a hand-lever, H, provided with aspringclutch, h, which holds the lever H at any de sired-point bymeshing into teeth on the circumference of the sector G Two arms, .g g,on the ends of the shaft G,

are connected by rods or links Z l to eyes in the bolts 11 b, whichclamp the slotted plates 6 6 together. It can now be readily seen that,

by the traverse of the lever H, the beams A A will be either elevated ordepressed, thus regulating both the depth and width of the furrows to becut by the plows E E. Any suitable mold-boards or cutters may beattached to the beams A A, and no land-side is required.- V

The object of giving an angular shape to the rim 1" of the wheel D is inorder that said wheel, as it runs in the furrow, may present a squaresurface to the land-side or wall of the furrow. The angle at which thewheel D is set opposes the plows angular determination of cut, and alsodiminishes the friction of said plows E E against the earth on thelandside. The resultant force between these opposing forces causes theplow, when drawn, to cut a furrow in a right line forward.

The object of making the plow-standards f f slotted is in order toallowthe plows or mold-boards E E to be set at different angles on the beamsA A', such changes being desirable for plowing different kinds of soils.For plowing mellow ground, the points of the plow should be more nearlyin line with the centers of the beams A A than when plowing through sod.In the latter case the point of the plow should be farther out from theline of the center of said beam.

In order to convert this double plow into a single one, .the two beams AA are removed, and also the tongue B, and the single plow shown in Fig.4. is substituted for the double beams A A. Said plow is secured by thesame bolts used for the double plows, one bolt passing through thesingle beam, and the other through its brace, as clearly shown in thedrawing. The tongue B is then secured to the single beam.

This whole machine is light and simple in construction, and the skeletonaxle-tree, securely braced as it is, binds the whole machine together,forming a durable, light, and strong combination of parts.

Having thus fully described this sulky-plow, as of my invention, Iclain1 1. The skeleton axle G, united by the vertical posts 0 c, andhaving a fixed wheel-spindle at one end, and at the other enda spindlecapable of oblique vertical adjustment, whereby the wheel is adjusted tostand vertically,

or at an inclined angle from the other, substantially as shown anddescribed.

2. The skeleton axle-tree 0, provided with the guide-braces 0 c, incombination with the slotted plates 0 e sliding thereon, and with theplow beam or beams A, whereby the plows are adjusted to any desirabledepth and width of furrow, substantially as shown and described.

3. The combination of the beam or beams A, plates e e, axle-tree 0,links 1 Z, shaft G, provided with arms g g, and lever H, Whereby thesaid axle-tree is operated, substantially in the manner hereinbeforedescribed, for the purposes set forth.

4. The block d swiveled vertically upon the axle a, and held at anyadjustment thereon by set-screw s, in combination with thewheel-spindled placed at right angles there- WILLIAM LEWIS OASADAY.
